Dialogic® DSI Signaling Interface Unit
Dialogic® DSI Signaling Interface Unit (DSI SIU) is a scalable, high performance, telecommunications Signaling platform, providing connectivity between the core SS7/SIGTRAN network and multiple distributed application servers. The DSI SIU can enable application developers to deliver high throughput Signaling applications to market quickly and cost-effectively using standard IP connectivity.
Features & Benefits
Worldwide protocol support (ITU-T, ANSI, China, Japan, etc.); wide range of protocols for both telephony-based (ISUP and BICC) and transaction-based operation (SCCP, TCAP, MAP, ANSI- 41, INAP, and CAMEL) as well as Global Title Translation and SS7 protocol monitoring
Facilitates global deployments and the ability to configure protocol variants at runtime
Software only deployment under VMware, KVM or AWS EC2 using a single OVF distribution
Allows the user to provision the optimal amount of resource and to select hardware platform of choice
Supports both browser and command line interface for OA&M in addition to SNMP
Facilitates comprehensive, user-friendly remote management using standard tools
Flexible capacity-based licensing
Allows increased platform capacity to be added over time to match deployment needs
Supports SIGTRAN (M3UA/M2PA) over IPv4 and IPv6 with option to deploy on commercial off the shelf server for support of E1/T1, SS7 Low Speed Links (LSL), High Speed Links (HSL) and ATM
Supports connectivity to legacy TDM equipment in networks that cannot offer full IP connectivity
Enables Broad Range of Signaling Applications
Applications which can be deployed with DSI SIU include standard network elements, such as SMS gateways, SMSC, SMS Routers, USSD gateways, GMLC and EIR in addition to customized applications such as Lawful Intercept, HLR interrogation, Welcome Roamer, or Missed Call Alerts.
SCCP Router and Signaling Gateway
The DSI SIU can optionally be configured as an SCCP Router or Signaling Gateway, providing high performance connectivity solutions for mobile networks. DSI SIU supports the ability to flexibly route messages (MTP3/M2PA or M3UA) and perform SCCP Global Title Translation.
Virtualized Deployment on Premise or Cloud-Based
Dialogic® DSI Signaling Interface Unit (DSI SIU) based on the Dialogic® DSI G5V Signaling Controller is a compact, cost-effective software-only virtualized telecommunications Signaling platform, providing core network connectivity for use in all-IP SIGTRAN Signaling environments. The G5V software-only appliance can be deployed on premises under hypervisors such as VMware or KVM or in the Cloud using an AWS EC2 environment. The software is supplied as a single OVF distribution. The DSI SIU on G5V allows network operators to provision the optimal amount of resource and select the hardware platform of choice.
Built-in Management
The DSI SIU features full built-in management capabilities with both command line and browser-based graphical user interface (GUI) for all operations, administration, maintenance, and provisioning functions. The GUI supports dynamic configuration, status and alarm monitoring, interactive control, and a wide range of diagnostic capabilities. A multi-user environment complete with password security, configurable user privileges and full audit trail ensures adherence to chosen security policy.
